【発明の詳細な説明】 粒状物を仕分けるための二重分離機 本発明は、粒状物、例えば、セメントの原料、或いは、セメントクリンカ−１或 いは、同様な鉱物原料を、粗い部分と、微粉部分とに仕分けるための分離機に関 し、前記粒状物は、ローラープレスの高圧力で粉砕され、粉砕材料は、凝塊物を 含んでいるので、更に処理する前に、材料をほぐされなければならない。[Detailed description of the invention] Double separator for sorting granules The present invention provides granular materials such as cement raw materials or cement clinker 1 or Or, it is related to a separator that separates similar mineral raw materials into coarse and fine particles. The granules are pulverized under high pressure in a roller press, and the pulverized material is free from agglomerates. contain, the material must be loosened before further processing.
粉砕された粒状物の粗い部分から微粉部分を仕分けるだめの分離機は、例えば、 空気分離機の形態でオーストラリア特許第２２０．０６９号、ドイツ特許第１． ９１３．９４６号、ヨーロッパ特許明細書第０．０２３．３２０号、ヨーロッパ 特許明細書第０．２１０．７２９号、デユーダ（Ｄｕｄａ）によるセメントブッ クｌ、第１５章（第３版 Ｂａｕｖｅｒｌａｇ ＧｍｂＨ。A separator that separates the fine part from the coarse part of the pulverized granules is, for example, In the form of an air separator Australian patent no. 220.069, German patent no. No. 913.946, European Patent Specification No. 0.023.320, Europe Patent Specification No. 0.210.729, Cement Book by Duda Cl, Chapter 15 (3rd edition Bauverlag GmbH.
Ｗｉｅｓｂａｄｅｎ ａｎｄ Ｂｅｒｌｉｎ、 １９８５年）に開示されている 。このような空気式分離機を、ローラープレスと関連して単一の分離機の形態で 使用すると、供給物は、普通は、例えば、ハンマーミルで行われるような別のほ ぐし行程を受け、この行程は、塊を分解するために分離行程に先立って行われる ので、このことは粉砕設備で個々の機械の数、及び、ハンマーミルの磨滅の増加 を必然的に伴う。ハンマーミル内の避けられない塵組成物により、塵が付いた材 料が分離機に搬送されることになる。Wiesbaden and Berlin, 1985) . Such a pneumatic separator can be used in conjunction with a roller press in the form of a single separator. When used, the feed is normally processed into another process, e.g. in a hammer mill. This process is carried out prior to the separation process to break up the lumps. Therefore, this increases the number of individual machines in the grinding equipment and the wear and tear of the hammer mills. inevitably accompanies. Due to the unavoidable dust composition in the hammer mill, dusted material The material will be conveyed to a separator.
連続的に増加する粉砕の部分はロラープレスの中で行われる傾向にあるので、こ れは、更に、分離機は、閉回路内の流量の増加により、連続的に増加する量の材 料を処理しなければならないことになる。その結果、材料は、同時に、粗くなり 、これにより、大きな磨耗と、分離機でのより大きな動力消費を生じさせる。This is because the continuously increasing part of the grinding tends to take place in the roller press. In addition, the separator can continuously increase the amount of material due to the increase in flow rate in the closed circuit. The charges will have to be processed. As a result, the material becomes coarser at the same time. , which results in greater wear and greater power consumption in the separator.
別のローラーでプレスされた供給物を微粉に粉砕するために筒型粉砕機を、引き 続いて使用すると、筒型粉砕機に供給された材料は、粒が筒型粉砕機内で大きな 粉砕体を必要とする大きな単一の粒を含み、或いは、筒型粉砕機が比較的細かい 細かさの半分程度粉砕した材料を供給されると、この乾燥した材料が筒型粉砕機 内で詰まるという問題を、今日まで有していた。A cylindrical crusher is pulled to grind the pressed feed into a fine powder with separate rollers. With subsequent use, the material fed into the cylindrical crusher will have a large grain size inside the cylindrical crusher. Contains large single grains that require a crushing body, or a cylindrical crusher is relatively fine When supplied with material that has been crushed to about half the fineness, this dry material is passed through the cylindrical crusher. Until today, I have had the problem of getting stuck inside.
更に、ヨーロッパ特許公開０２５０７４７号（ＢＰ−Ａ２−０２５０７４７）か ら、搬送ガス中に懸濁された粒状物を仕分けるための空気分離タイプの二重分離 機が知られており、この分離機は、上方粗粉分離機と、この粗粉分離機と直列に そして直接連結された下方微粉分離機とを備え、両分離機は垂直シャフトの廻り をまわるローターを備え、各ローターは調整可能なルーバブレードを有し、上方 即ち粗粉分離機は、筒型粉砕機のような粉砕装置からの凝塊物を含む粗い材料を ほぐすためのアームを備える水平遠心衝撃粉砕機であり、入れられた材料は、粗 粉分離機の上方部分に取付けられた入口ダクトを通して分離機に入れられ、そし て、衝撃粉砕機のアームの間に形成された空間は、搬送ガスに懸濁された粗い部 分の分離された部分が分離機ハウジングを通って、下方分離機内での更なる処理 のため下方分離機に送られるようにする。Furthermore, European Patent Publication No. 0250747 (BP-A2-0250747) air separation type double separation for sorting particulate matter suspended in the carrier gas. This separator has an upper coarse powder separator and a coarse powder separator in series with the upper coarse powder separator. and a directly connected lower fines separator, with both separators running around a vertical shaft. each rotor has adjustable louver blades that rotate upward. In other words, a coarse powder separator separates coarse material containing agglomerates from a crushing device such as a cylindrical crusher. A horizontal centrifugal impact crusher with a loosening arm, the input material is into the separator through an inlet duct installed in the upper part of the powder separator, and Therefore, the space formed between the arms of the impact crusher contains the coarse particles suspended in the carrier gas. The separated parts pass through the separator housing and further processing in the lower separator. so that it is sent to the lower separator.
前述の単−分岐機設備と比較すると、ヨーロッパ特許０２５０７４７号（ＥＰ− Ａ２−０２５０７４７）による二重分離機は、別体のハンマーミルのような外部 はぐし機を有している前述の単−分離様装置とは、外部はぐし機が組み込み型の ほぐし機として機能する上方粗粉分離機によって置き換えられていることが異な るだけであり、従って、この二重分離機の使用は、原則として、単−分岐機設備 を関連して説明したような欠点と同じ欠点を必然的に伴う。In comparison with the single branch equipment described above, European Patent No. 0250747 (EP- A2-0250747) double separator is a separate hammer mill-like external separator. The above-mentioned single-separation-like device that has a peeler is different from the one in which the external peeler is built-in. The difference is that it has been replaced by an upper coarse separator which acts as a loosening machine. Therefore, the use of this double separator is, in principle, entails the same drawbacks as those described in connection with.
従って、本発明は、ローラプレスと一緒に、そして選択的には筒型粉砕機と一緒 に使用でき、上記欠点を回避する分離機を提供することを目的とする。Therefore, the present invention can be used together with a roller press and optionally with a cylindrical crusher. It is an object of the present invention to provide a separator which can be used in the following manner and which avoids the above-mentioned drawbacks.
この目的は、請求の範囲１に記載の前文部分で言及され、該請求の範囲の特徴こ の分離機の更なる特徴は、請求の範囲２乃至５の内容から明らかになるであろう 。This object is mentioned in the preamble of claim 1 and features of that claim. Further features of the separator will become clear from the contents of claims 2 to 5. .
本発明の驚くべき新規事項は、かくして、微粉分離機の下に粗粉分離機を設置し 、これにより、処理製品のよりきれいな微粉を得て、（筒型粉砕機のための）中 間的な微粉を生産する可能性及び粗粉分離段階を通過させる必要性なく中間的な 微粉を受け取る可能性を得る。The surprising novelty of the present invention is thus that the coarse powder separator is installed below the fine powder separator. , thereby obtaining a cleaner fine powder of the processed product and (for cylindrical crushers) Possibility to produce intermediate fines and intermediate without the need to pass through a coarse separation stage Gain the possibility of receiving fine powder.
このような分離機は、ローラープレスから粗粉分離機への供給量を現在知られ難 度合い（低い「切断寸法」）を達成でき、その結果、分離後全体として低い特定 の分離作用を得る。Such a separator can reduce the feed rate from the roller press to the coarse separator, which is currently unknown. (lower “cutting dimensions”), resulting in an overall lower specificity after separation. obtains the separation effect.
粗粉分離機で分離された粗い材料の粗い部分は、ローラープレスに戻され、こに よって、前記プレスのより効率的な使用の可能性を増加させ、一方、微粉分離機 で分離された微粉材料の粗い部分は、小さな粉砕体を使用する単一チャンバ式の 閉回路ミルである筒型粉砕機に送られ、これにより、単一の大きな粒でも極めて 細かい材料のいずれでもない、中間の大きさの部分のみが筒型粉砕機に供給され るという事実から、筒型粉砕機の効率が改善される。The coarse part of the coarse material separated by the coarse powder separator is returned to the roller press where it is Thus, increasing the possibility of more efficient use of the press, while the fines separator The coarse part of the fine powder material separated by It is sent to a cylindrical crusher, which is a closed circuit mill, which allows even a single large grain to be Only medium-sized portions, not any of the fine materials, are fed into the cylindrical crusher. The efficiency of cylindrical mills is improved due to the fact that
